My research interests primarily focused on electronic structures and (charge, spin
and phonon) transport, in electric or magnetic field, through various nano
materials, such as carbon nanotube, graphene, dna, molecules, and 2d electron
gas semiconductor structures. We carry out research in the field of
computational condensed matter physics.
My current interests mainly lie in developing and/or using direct first-principles methods, first-principles-based techniques and semi-empirical approaches to calculate properties of ferroelectrics, magnetic compounds, multiferroics, semiconductors and nanostructures.
